DETAILED DESCRIPTION OF THE INVENTION

Referring to FIGS. 1-4, a multifunction flashlight 10 in accordance with the present invention is shown. The multifunction flashlight 10 defines a front end 101 and an opposing rear end 102. Further, the multifunction flashlight 10 comprises a light source 11, a light source switch 21, a focus adjustment device 31, a plurality of tools 41, an emergency exit hammer 51, a release switch 61, a seat belt cutter 71 and a USB jack 81.

The light source 11 is mounted in the front end 101 of the multifunction flashlight 10, comprising an LED light 13. In this embodiment, the LED light 13 is a variable color LED light 13. Further, the LED light 13 is controllable to emit white light for the purpose of illumination, or red light for the purpose of warning. Further, when the LED light 13 is controlled to emit red light, the red light is emitted in a flashing manner (not shown).

The light source switch 21 is mounted on the body of the multifunction flashlight 10 near the front end 101, thereby allowing the user to conveniently operate when holding the multifunction flashlight 10. The light source switch 21 is operable to switch on/off the LED light 13. Since the LED light 13 in the present preferred embodiment is a variable color LED light, the light source switch 21 can also switch the LED light 13 between a white light mode and a red-light mode. Further, the light source switch 21 is a multi-step push button switch. However, this multi-step push button configuration is not a limitation. Another configuration, such as a rotary switch, can be used as a substitute. The focus adjustment device 31 is mounted on the body of the multifunction flashlight 10 between the light source 11 and the light source switch 21, and operable to zoom in or out the light beam of the LED light 13. In the present preferred embodiment, when the focus adjustment device 31 is pulled backwards, the light beam of the LED light 13 is shifted from a concentrated mode to a scattered mode; on the contrary, when the focus adjustment device 31 is pushed forwards, the light beam of the LED light 13 is shifted from the scattered mode to the concentrated mode.

The multiple tools 41 are respectively pivotally connected to the rear end 102 of the multifunction flashlight 10. The multiple tools 41 include a small knife 42, a small scissors 43, a bottle opener 44, a flathead screwdriver bit 45, a Phillips screwdriver bit 46 and a hex wrench 47. Each tool 41 can be biased and received in the multifunction flashlight 10.

The emergency exit hammer 51 has a pointed tip 53. Further, the emergency exit hammer 51 is pivotally connected to the rear end 102 of the multifunction flashlight 10 and can be biased and received inside the multifunction flashlight 10. In the present preferred embodiment, the tools 41 and the emergency exit hammer 51 are arranged back to back.

The release switch 61 is mounted on the body of the multifunction flashlight 10 near the rear end 102, thereby allowing the user to conveniently operate when holding the multifunction flashlight 10. Triggering the release switch 61 can bias the emergency exit hammer 51 to move the pointed tip 53 out of the multifunction flashlight 10. In the present preferred embodiment, the release switch 61 is of a push button design, however, this push button design is not a limitation. Other designs, such as the DIP switch design can be used as a substitute.

The seat belt cutter 71 comprises a profile slot 73 and a cutter blade 75. The profile slot 73 curves inward from the surface of the body of the multifunction flashlight 10 and tilts from front to back. The cutter blade 75 is mounted in the profile slot 73. Further, the cutter blade 75 is spaced below the top open side of the profile slot 73 at a predetermined distance. In the present preferred embodiment, the seat belt cutter 71 is disposed near the rear end 102 of the multifunction flashlight 10.

The USB jack 81 is mounted on the body of the multifunction flashlight 10. Further, in the present preferred embodiment, the USB jack 81 is a power jack for battery charging (since the battery in the present preferred embodiment is a rechargeable power storage device of the common technology, it is not shown in the drawings). Thus, the multifunction flashlight 10 can be charged with an external power source.

The multifunction flashlight 10 further comprises a protective shell 91 attached to the front end 101 of the multifunction flashlight 10. The protective shell 91 has a plurality of protruding portions 93 equiangularly spaced around a top edge thereof. The protective shell 91 is adapted for protecting the light source 11 against the impact of an external glass or other hard objects. The protruding portions 93 can be used as foot members of the protective shell 91 to support the multifunction flashlight 10 on a planar surface (flooring surface or tabletop) in an erect position. In addition to

the advantage of being easy to take, the multifunction flashlight 10 in the erect position is less susceptible to displacement upon a slight vibration, avoiding resulting in lossor damage.

However, if the light source 11 will not be impacted when you use the multifunction flashlight 10, the protective shell 91 can be eliminated. Therefore, the protective shell 91 is not a requisite component. However, without mounting the protective shell 91 at the front end 101 of the multifunction flashlight 10, you cannot use the protective shell 91 as a seat for the multifunction flashlight 10.

The multifunction flashlight 10 further comprises a light transmissive ring 95. The light transmissive ring 95 is mounted on the body of the multifunction flashlight 10 in the front end 101. If the multifunction flashlight 10 is equipped with the protective shell 91 and the LED light 13 is controlled to emit a red warning light, the user can use the protruding portions 93 of the protective shell 91 as seat means to support the multifunction flashlight 10 on the floor in an erect position, enabling the emitted red warning light to go through the light transmissive ring 95 toward the outside, avoiding significant reduction of the red light transmittance due to the downward facing position of the LED light 13. Therefore, the arrangement of the light transmissive ring 95 greatly increases the overall light transmission area of the multifunction flashlight 10. If it is not necessary to increase the light transmission area, the light transmissive ring 95 can be eliminated. Therefore, the light transmissive ring 95 is not a requisite component.

After understanding the structural details of the present invention, the application of the multifunction flashlight 10 is explained hereinafter.

Referring to FIGS. 1-3, when using the multifunction flashlight 10 for illumination, hold the body of the multifunction flashlight 10 with one hand and press the light source switch 21 to switch on the LED light 13, driving the LED light 13 to emit white light for illumination. At this time, you can pull the focus adjustment device 31 forward or backward to zoom in or out, adjusting the lighting range. Thereafter, you can press the light source switch 21 to shift the LED light 13 from the white light mode to the red-light mode for warning if desired. When you press the light source switch 21 again, the LED light 13 will be shifted from the red-light mode back to the white light mode. If you press the light source switch 21 again, the LED light 13 is immediately returned to OFF state.

When using the multifunction flashlight 10 for cutting off a seat belt, insert the seat belt into the profile slot 73, and then pull the seat belt against the cutter blade 75 in the direction away from the profile slot 73. At this time, the cut part of the seat belt will be moved out of the profile slot 73. This procedure is repeated again and again until the seat belt is completely cut off, thereby avoiding the situation in which the person is trapped by the seat belt and cannot smoothly turnaround.

Referring to FIGS. 1, 2 and 4, when using the multifunction flashlight 10 for breaking glass, press the release switch 61 to release the emergency exit hammer 51, enabling the emergency exit hammer 51 to bias the pointed tip 53 toward the outside of the multifunction flashlight 10, and then apply pressure to the emergency exit hammer 51 to strike the pointed tip 53 of the emergency exit hammer 51 against the glass, thereby breaking the glass. After the usage, push the emergency exit hammer 51 back into the inside of the multifunction flashlight 10 by hand.

When using the multiple tools 41, you can turn the selected tool 41 toward the outside of the multifunction flashlight 10. After the usage, you can turn back the selected tool 41 and receive it in the multifunction flashlight 10.

Thus, if you find that the seat belt is wrapped around a person and you cannot unbuckle the seat belt lock, you can use the seat belt cutter 71 to cut off the seat belt so that the trapped person can smoothly turnaround.

Further, if people are trapped due to the window's inability to be opened, you can use the emergency exit hammer 51 to break the window glass so that the trapped people can successfully escape.
